WORD-COUNTING ATTACHMENT FoR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 735,468, dated August 4, 1903. Application filed November 1, 1902; Serial No. 129:630. (No model.)

To all whom, it 710a concern. 7

Be it known that we, JAMES G. COLEMAN and LUTHER WILHITE, both citizens of the United States, and residents of Cleburne, in the county of Johnson and State of Texas, have invented a new and Improved WVord- Counting Attachment for Type-lVriters, of which the following is a full, clear, and exact description.

This invention relates to improvements in word-counting or registering attachments for type-writing machines, the object being to provide a device for this purpose of simple construction that may be readily attached to the machine and by means of which the number of words printed will be accurately indicated.

lVe will describe a word-counting attachment for type-writers embodying our invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similarcharacters of reference indicate corresponding parts in all figures.

Figure 1 is an inverted plan View of a typewriting machine, showing a word-counting device embodying our invention attached thereto. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a similar section, but showing the parts in a different position. Fig. 4 is a side elevation of the attachment, and Fig. 5 is a'plan view thereof.

The attachment comprises aseries of register-disks 5, arrangedin a casing 6 and operated one from another in the usual manner. The casing 6 is mounted on an arm 7, removably attached to a side rail 8 of the machine-frame. As here shown, the arm 7 has an upright portion 9 for engaging against the inner side of the rail 8, and pivoted to the upper end of this portion 0 is a clip 10 for engaging against the outer side of the rail,

and this clip is secured to the upright 9 by means, as here shown, of a screw 11. On the shaft supporting the register-disks is a lever 12, designed to be engaged bya projection in the form of a roller 13, secured to an arm 14 on the space-bar 15.

Mounted to swing on a stud 16, extended from the arm 7, is a curved stop-finger 17. This stop-finger has a horizontally-disposed lower member 18 for engaging its free end against the under side of the arm 7 to limit the downward movement of the finger 17, and the said finger 17 is moved to normal position by means of a spring 19, attached at one end to said finger below its pivotal point and at its other end to the arm 7. The finger 1.7 is provided with a notch 20 for receiving a roller 21 on the end of the lever 12, and it will be noted that the upper wall of this notch is inclined upward and rearward, so that the roller will be readily released upon a downward pressure on the lower portion of the finger.

Attached to the front rail 22 of the machine-frame are rearwardly-extended crossed spring yielding bars 23, which pass underneath the keys of the machine, and at the rear ends of these rods 23 is a cross-bar 24, designed to be engaged by the finger-levers. From the rods 23 a finger 25 extends laterally and engages upon the upper side of the extension 18. A spring 26, attached at one end to the arm 7 and engaging at its other end with a pin on the lever 12, serves to return said lever to its normal position when released.

In operation when the space-bar is moved downward at the end of a word the projection or roller 13 by engaging with the lever 12 will force the same downward and cause a rotary movement of one or more of the numeral-disks. When thelever reaches the limit of its downward movement, it will engage in the notch 20 and be held to insure the rotary movement of thedisk or disks. Upon the operation of a fingerdever for the first letter of the next word the rods 23 will be forced downward, and consequently the arm 25 will rock the finger 17, so as to permit the lever 12 to move upward.

It will be noted that the cross-bar 24: does not extend under certain finger-levers at the sides, as these lovers are for other purposes than that of printing letters, such as shifting from lower to upper case and printingcertain characters or punotuations which should not be counted as words, and therefore these finger-levers should notrelease the lever 12.

To ascertain the number of words in a letter or document, subtract the amount that is first registered from the final amount after the letter or document has been written and add the tenths and multiply by ten.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. A word-counting attachment for typewriters, comprising a register, supported on the machine-frame, an operating-lever extending from the shaft of the register and'opcrating in one direction by a downward movement of the space-bar, a swinging finger having a notch to receive a part carried by said lever, and means actuated by a finger-lever for releasing said operating-lever.

2. A word-counting attachment for typewriters, comprising register-disks supported on the machine-frame, a lever extended frem the shaft thereof and operated by a downward movement of the space-bar of the machine, a curved finger mounted to swing and having a notch, a roller on said lever for engaging in notch, and means operated by a downward movement of a finger-lever for releasing said finger from the roller.

3. A word-counting attachment for typewriters, comprising register-disks, an arm supporting said disks, means for clamping said arm to the machine-frame, a lever on the.

shaft of the register-disks, means carried by an arm of the machine space-bar for engaging with said lever, a curved finger pivoted to the arm and having a notch, the upper wall of said notch being inclined, a roller 011 the le- Ver for engaging in said notch, a forward projection at the lower end of said finger for engaging at its free end against the under side of the arm, a spring for moving the finger to normal position, spring yielding rods extended from the machine-frame, and a cross-bar on said rods adapted to be engaged by printing-finger levers.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
